WThe ocellated eagle ray is a species of cartilaginous fish in the eagle ray family Myliobatidae. It is found in the tropical Indo-West Pacific region. In the past it was included in the spotted eagle ray, a species restricted to the Atlantic after the split.
WThe Australian ghostshark is a cartilaginous fish (Chondrichthyes) belonging to the subclass Holocephali (chimaera). Sharks, rays and skates are the other members of the cartilaginous fish group and are grouped under the subclass Elasmobranchii. Alternative names include elephant shark, makorepe, whitefish, plough-nose chimaera, or elephant fish.

WHaemulon flavolineatum, the French grunt, is a species of grunt native to the western Atlantic Ocean from South Carolina and Bermuda to Brazil as well as the Gulf of Mexico and the Caribbean Sea. The French grunt travels in schools among coral and rocky reefs where it occurs at depths of from 0 to 60 metres. Their bodies are yellow with horizontal silver stripes running the length of, and diagonally-oriented stripes below the lateral line of their bodies. All of the fins are yellow. This species can reach a length of 30 centimetres (12 in) TL though most do not exceed 17 centimetres (6.7 in). This species is important to local commercial fisheries and are popular in public aquariums.
WThe hampala barb is a relatively large southeast Asian species of cyprinid from the Mekong and Chao Phraya basins, as well as Peninsular Malaysia and the Greater Sundas. It prefers running rivers and streams, but can be seen in most freshwater habitats except torrents, small creeks and shallow swamps. This predatory species reaches up to 70 cm (2.3 ft) in length and it is common at half that size.
WThe Indian anchovy, also known as Hardenberg's anchovy, is a species of oceanodromous fish in the family Engraulidae. It is known as Handalla (හැදැල්ලා) in Sri Lanka, where it is widely sold at most markets and supermarkets. It is widely used as a live or dead bait in tuna fishery.

WPterophyllum scalare, most commonly referred to as angelfish or freshwater angelfish, is the most common species of Pterophyllum kept in captivity. It is native to the Amazon Basin in Peru, Colombia, and Brazil. Particularly to the Ucayali river in Peru, the Oyapock River in French Guiana, the Essequibo River in Guyana, the Solimões, the Amapá, and the Amazon rivers in Brazil. It is found in swamps or flooded grounds where vegetation is dense and the water is either clear or silty. Its native water conditions range from a pH of 6.0 to 7.0, a water hardness range of 3 to 10 °dH, and water temperature ranging from 26 to 30 °C. This is the species of angelfish most frequently found in the aquarium trade. A similar P. scalare exists in the Orinoco. They are of the same size and shape, the only difference being its stripes: the Orinoco P. scalare has thinner, but dual stripes.
WThe Siamese algae-eater is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia, including the Chao Phraya and Mekong basins as well as the Malay Peninsula. Its natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae-eater should not be confused with the flying fox or the false siamensis , lacking the distinctive black bands of the former.
